Brain Tumor Classification
Brain Tumor Classification
Tumors can be categorized into cancerous (malignant) and non-cancerous (benign) types, with primary tumors originating within the brain and secondary tumors spreading from other parts of the body. The symptoms vary based on the affected brain region and may include persistent headaches, seizures, vision problems, vomiting, and changes in mental function. Notably, morning headaches that alleviate with vomiting are characteristic. As the disease progresses, individuals may experience difficulties in walking, speaking, or sensation, leading to potential unconsciousness.
A brain tumor refers to the abnormal growth of cancerous or non-cancerous cells within the brain. Tumors can either originate in the brain or result from cancer spreading from other body parts. Symptoms encompass new or intensified headaches, blurred vision, loss of balance, confusion, and seizures. Some cases may present with no noticeable symptoms. Treatment options involve surgery, radiation, and chemotherapy.
Brain tumors are relatively rare compared to other types of cancers, accounting for about 1-2% of all cancer diagnoses.
The incidence of brain tumors varies globally, with differences in rates among countries and populations.
The exact causes of most brain tumors are still not well understood. Some risk factors and associations have been identified, but in many cases, the cause remains unknown.
Known risk factors may include exposure to ionizing radiation, certain genetic conditions, family history, and certain environmental factors.
Headache: Acute or persistent
Muscular: Difficulty walking, instability, muscle weakness, coordination problems, weakness on one side of the body, or weakness in the arms and legs
Whole body: Dizziness, fatigue, or vertigo
Gastrointestinal: Nausea or vomiting
Sensory: Pins and needles or reduced sensation of touch
Cognitive: Inability to speak or understand language, mental confusion
Other common symptoms: Blurred vision, difficulty speaking, personality changes, seizures, or sleepiness
Diagnosis and Treatment: Diagnosis often involves imaging studies such as MRI or CT scans, and sometimes a biopsy may be needed for further characterization.
Treatment options include surgery to remove the tumor, radiation therapy, and chemotherapy.
The choice of treatment depends on factors such as the type and grade of the tumor, its location, and the overall health of the patient.
